Abstract: 1514599 Electronic timepieces K KAWAMURA and Y KAWAMURA 12 Nov 1976 [14 Nov 1975] 47259/76 Heading G3T [Also in Divisions G4 and G5] In a matrix display fountain with rows of nozzles 3 arranged in ascending steps, each nozzle is controlled by an electromagnetic valve 7 operated by a control circuit to display numerals, characters etc. The rows of nozzles, e.g. 7 rows of 47 nozzles, Fig. 8 (not shown), may be under a single sloping perforated plate, Figs. 36, 37 (not shown), or in long 'ponds' 2 each possibly with a front guard plate 10, or each nozzle may be in an individual box, Fig. 32 (not shown), in all cases mounted above a collecting pond 1 from which the water is recirculated by pump 4 to a plenum chamber 9 with excess pressure by-pass valve 8. Other decorative jets or flow from a header tank may be added, all draining to pond 1 which may hold fish. The display is shown as a digital clock operated by division from the mains frequency, switching for 10 minutes in each hour to display e.g. Roman, Japanese or Chinese characters alternately each hour from two optical punched card readers 13-1,2 or other data storage devices. A coin operated manually controlled display facility is provided e.g. by a third card reader 15 overriding other displays for a fixed period after coin insertion at 16. For clock display the columns are divided into groups, (Fig. 6) corresponding to two digits for hours and two for minutes of a 12 hour clock with (:) separator (24 hour display being alternative); the valves of each group being controlled by BCD signals from stages in a frequency divider chain, Fig. 11 (not shown), operating through decoder 14 and gates 18. Other signals from the divider chain operate selector 12 for 10 minutes in every hour to inhibit clock signals from passing gates 18 and activating alternately memories 13-1,2. Alternatively the display may be controlled by a continuously moving tape, Figs. 17A, B (not shown), from which a message is stored to remain as a static display until the tape has moved on to a completely new sector, when the message is changed en bloc. Further the display may be set by wiring but with groups of columns corresponding to characters gated by brushes rotating above fixed interrupted facial slip-rings Fig.24 (not shown) so as to be activated cumulatively. Alternate displays of Japanese and Roman characters may be produced by similar slip-rings with two interruptions Fig.29 (not shown).

Abstract: 1,093,381. Hydraulic brakes. GIRLING L t d Dec. 4, 1964 [Dec. 13, 1963], No. 49254/63. Heading F2F. In a master cylinder of an hydraulic braking system having a connection 36 to pump or other source pressure controlled by a normally closed first valve 38, 39 and a connection 28 to a replenishment reservoir controlled by a normally open second valve 25, 26, the said first and second valves are respectively closed and opened by a pedal-operated rod 14 which extends through the master cylinder piston 12 and which has limited axial movement relative to the said piston so that pressure fluid can be admitted to the cylinder chamber 11 and fed to the brakes through the outlet 42 on movement of the rod 14. The head of the piston is counterbored to receive the head 15 of the rod with a limited axial clearance 22. The rod has a bore 23 to slidably receive a sleeve 24 surrounding the stem 25 of a conical valve 26. On initial movement to the left the valve seats to close passage 27 leading to the reservoir connection 28 under the action of spring 33 acting against a dished plate 32 carried by the bell-ended sleeve 24. On further movement of the rod, the top of plate 32 abuts against and pivots on a stop 43 such that the bottom of the plate actuates a thrust pin 39 to open valve 38 controlling the passage of fluid from a pressure source connected at 36 to pass into the cylinder bore 11 and out through union 42 to the brake cylinders. On failure of the pressure source further leftwise movement of the rod 14 takes up the piston/rod head clearance 22 and piston 12 is moved forward to actuate the brakes in the conventional man ner, non-return valve 37 preventing fluid loss through inlet 36. In a further embodiment, Fig. 4 (not shown), the piston/rod head arrangement is similar to that described above, but the fluid control valve (68), admitting fluid to the cylinder from a pressurised source, is disposed in a boss on the cylinder body with its axis inclined to the cylinder axis and is opened by a shoulder (70) of the rod engaging a thrust pin (69). The reservoir outlet (56) is controlled by a valve (56) whose stem slides in a rod bore (59) and which is retained therein by a spider (62). In a further embodiment, Fig. 6-10 (not shown), the control valve and reservoir valve are formed by a pair of tilting valves axially staggered along the cylinder bore so that a flanged, spring-loaded sliding sleeve on a pedal-operated rod initial permits the normallyopen reservoir to close prior to opening the normally-closed control valve.
